Device for operating rear side windows of convertible vehicles
Abstract
A device that includes at least one slider joined to a window
which slides along the rail defining the trajectory for the window.
The trajectory is defined by a departure angle formed by the
vertical and initial upper curvature of the rail which is
.+-.45.degree. and the curvature radius of the aforementioned
trajectory which is about 0 to 500 mm. The device includes a means
of adjusting the position of the device with regard to a door
including an upper pivoting axle on the rail which allows the
device to tilt to fit it in the door with two lower transversal
screws for lateral adjustment, and one screw on the slider for
adjusting the window with regard to the rail and the slider.

Claims
1. An operating device for a vehicle which includes at least one
slider joined to a window which slides along a rail which defines a
window trajectory, the window trajectory being determined by an
angle of departure formed by a vertical and initial upper curvature
of the rail and by a curvature radius of the window trajectory; and
a means of adjusting the position of the device with regard to a
door of the vehicle, wherein the departure angle is between
+45.degree. and -45.degree. and curvature radius is in the interval
between 0 mm to 500 mm.
2. An operating device in accordance with claim 1, wherein the rail
has a trajectory including several curves with corresponding
changes in curvature without points of inflection.
3. An operating device in accordance with claim 1, wherein the
means of adjusting the position of the device include an upper
pivoting axle on the rail which allows the device to tilt slightly
to fit into the door, using at least two lower transversal screws
for lateral adjustment, and at least one screw on the slider which
allows the position of the window to be adjusted with regard to the
rail and the slider.
Description
[0001] This is an operating device comprising of at least one
sliding part operated by an electrical motor using cables as is
normal in the technique. The slider on the operating device is
attached by any suitable means to the lower part of the cabriolet
vehicle window for example using a holding clamp. This sliding
device may slide along a rail which defines the trajectory of the
window it is operating.
[0002] Due to the shape of the vehicle, the trajectory of the rear
side windows on cabriolet vehicles is usually curved with at least
one inflection. This means that mechanisms to operate these windows
are complex and costly.
[0003] In accordance with the invention there are two fundamental
design parameters which may very simply solve the problems
encountered in devices described above. These parameters directly
concern the trajectory which the vehicle window follows and are:
the angle of departure formed by the vertical and initial upper
curvature of the rail: and the radius of curvature for this
trajectory, which logically corresponds to the curvature of the
device's rail.
[0004] In particular, operating tests have shown that the angle of
departure must be between +45.degree. and -45.degree. and that the
aforementioned radius of curvature must be in the interval between
.infin. (straight trajectory) and 500 mm.
[0005] With this operating device for the side rear windows on
cabriolet vehicles in the invention, it is possible to have one
single rail; thereby structurally simplifying the overall
mechanism. Also, the invention means that this single rail has a
trajectory with several curved sections with corresponding
curvatures.
[0006] There are important advantages from the above features.
Firstly, the cost is drastically reduced, because operating devices
of this type of window has a rail with three guides to operate the
glass due to the trajectory (curved and with infections) which has
been described in its operation. Moreover, the invention has one
single rail with the aforementioned parameters in a simpler
configuration to reduce development and design time. As a
consequence of the simplification of the device, noise and
operating vibrations are reduced.
[0007] The device in the invention also includes ways of adjusting
the position with regard to the vehicle's door formed by an upper
swivel axis on the rail which allows the device to tilt slightly in
order for it to adjust to the vehicles door. It also has at least
two lower transversal screws to laterally adjust the device's
position and at least one screw in the slider to allow the class to
be positioned with regard to the overall slider--rail
mechanism.
[0008] The features and advantages of the device in this invention
shall be become clearer from the detailed description of a
preferred implementation. This description is given hereinafter as
a non-limiting example with reference to the drawings.
In these drawings:
[0009] FIG. 1 is a side view of the operating device for rear side
windows in cabriolet cars in accordance with the invention showing
the aforementioned device without the window for reasons of
clarity.
[0010] FIG. 2 is a front view of the side window operating device
from FIG. 1.
[0011] Figures of 3 to 5 are side views showing the sequence of
movements of the window when the device is operating.
[0012] The operating device (1) which is shown by way of an
example, comprises a sliding piece (2) equipped with a clamp to
hold the lower edge of the window (4) on the cabriolet vehicle as
shown in FIGS. 3 to 5 of the attached drawings. The sliding piece
(2) is operated by cables (5) and an electric motor (6) which moves
along the rail (7). The rail (7) for the device (1) defines the
mainly curved trajectory which the window must follow (4) in its
operation following the different positions shown in FIGS. 3, 4 and
5.
[0013] In FIG. 1, the two main parameters for the window's (4)
trajectory upwards and downwards are defined. These are:
[0014] (.infin.): angle of departure formed by the vertical and
initial upper curvature of the rail (7): and
[0015] (R): for the rail trajectory (7) from the centre of the
curve (C).
[0016] In accordance with tests carried out, it has been found that
the angle of departure (.infin.) must be between +45.degree. and
-45.degree. and that the radius of curvature (R) must be between
.infin. (straight rail (7)) and 500 mm (maximum rail curve).
[0017] There are ways of adjusting the position in terms of the
vehicle's door (not shown). These methods comprise an upper swivel
axle (8) on the rail (7). This upper swivel axle (8) also acts as a
fixing axle and allows the rail (7) to tilt slightly to adjust it
in the vehicle's door. Adjustment also includes 2 lower transversal
screws (9, 10) which operate to laterally regulate the position of
the device. Finally the aforementioned adjustment includes screws
(in 11, 12 a) on the slider as shown in FIGS. 3 and 4, which allow
the glass to be adjusted with regard to the rail--slider (7, 2)
equipment on the device (1).
[0018] The means of adjusting the position with regard to the
vehicle's door allow the device (1) to be widely fitted to the
vehicle, which easily compensates for any likely deviation from the
design as well as operating wear and tear and tolerances.
[0019] Having sufficiently described how the operating device for
rear side windows on cabriolet vehicles is formed for this
invention using the attached drawings, it is understood that any
modification to the detail of the mention which is judged to be
suitable may be made whenever the essential features of the
summarised invention in the following claims are not altered.
